Well if it's gaming you're going to use it for, an onboard intel graphics card won't work for you either. I'm sorry mate. There's two reasons to buy a state of the art PC.
One of them is video editing, the other one is gaming.
I suggest you spend at least 700 dollars and it's definitely word building a PC yourself of let someone you know build it for you. The PC you're opting is already old. That's the whole reason why it's cheap. I bought a PC faster than that (3ghz core2duo, 4gb ram, geforce 9600gt, 1000GB HD) back in 2007. It's just old hardware sold new.
What you need is a decent videocard (I'm not into videocards until I have to buy them, but I'm pretty sure ATI and NVIdia still make kickass videocards), at least an intel i5 processor, at least 4gigs of ram and a nice quick and big harddisk if you want to play games in the future. Sorry

I don't really understand that site you're using.
I don't know what it's like there, but compared to what you can buy here it's really really very expensive and they provide you with 250gb harddisks and 2gigs of ram.
It's almost impossible to buy a PC with less than a 1tb (1000gb) harddisk and 4gb of ram.
The site seems a bit odd.

This would be nice for you
But this one would cope with your needs just fine too

In the end, a ready made PC is a lot more expensive than one you build yourself.
I suggest you compile it yourself. If you don't, I think Dell is a pretty good choice.
Whatever you do, avoid Acer, avoid Packard Bell.
And to the ones who don't agree; Feel free. It's just my two cents
